OIL-CAN PUMP.

' Application filed June 23, 1923. Serial. No. 647,269.

To all whom it may concern:

Be it known that I. EDWARD Hnsrnn, a subject of the King of Great Britain, of the town of Wilcox, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Oil-Can Pumps, of which the following is the specification.

The invention relates to improvements in oil can pumps and an object of the invention is to provide a pump attachment for the can which can be removed as a unit from the oil can or container and which is arranged so that it can be readily operated by thumb pressure.

A further object is to construct a pump which will efiectively discharge oil from the can in either the vertical or horizontal position and which is designed such that it will discharge practically all the oil from the can.

A further object is to construct the device in a comparatively cheap and durable manner.

With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Fig. 1 is a side view of an oil can provided with my pump.

Fig. 2 is a plan view of the device.

Fig. 3 is an enlarged detailed vertical sectional view centrally through the device.

Fig. 1 is an enlarged detailed vertical sectional view through the check valve.

Fig. 5 is an enlarged detailed horizontal sectional view centrally through the suction valve.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The can or oil container 1 is provided with the customary handle 2 and finger grip 3 at one side and is fitted with the filling plug a at the other. The top of the can is provided with a comparatively large opening 5 surrounded by a comparatlvely large externally screw threaded upstanding flange or collar 6. The opening 5 which is circular has the centre point thereof positioned to the side of the vertical axis of the can body. Internally at the side opposite to the handle the can is provided with a semi-circular horizontally disposed partition or oil stop 7 which is situated approximately halt-way up the side of the can.

The pump utilized for forcibly expelling the oil from the can is shortly described and it is arranged so that it can be attached to the can as a unit, being held in place by a screw threaded cap 8 applied on the flange 6; Within the cap, which it will be observed is provided with an inturned flan e, Ilocate a disc like closure plate 9 adapted to seat on said flange 6 and to be held firmly in place by the flange of the cap when the same is screwed tightly down. A washer 10 is placed between the cap and the collar to prevent any possibility of oil leakage.

The oil delivery spout'll passes centrally through the plate 9 and is permanently attached thereto. The upper end of the spout tapers as is customary and the lower end thereof opens to the interior of a horizontally disposed oil box l2permanently secured to the spout. A check valve 13 of any approved type is inserted in the lower end of the spout, the check valve permitting of the flow of oil from the box to the spout but preventing a return flow from the spout to the box. The ends of the box are closed and one end, which is inset, is provided with a centrally positioned valve opening 14: normally closed by a suction valve 15, such latter valve being in the form of a flat strip or plate carrying a pair of guide stems l6 and 17 which pass slidably through the end of the box at opposite sides of the valve opening and are fitted with springs 18 normally acting to hold the said valve closed.

A cylinder 19 is permanently secured to the opposite end of the box, said cylinder having the lower end thereof opening to the interior of the box and the upper end thereof contracted and communicating with a guide tube 20 which passes upwardly through the plate 9 and terminates in any suitable type of stuifing box 21. A plunger or piston 22 provided with the customary washers is slidably mounted within the cylinder and the piston is fitted With an extending piston rod 23 passing slidably upwardly through the tube and stuffing box and terminating in a thumb grip 2e permanently attached thereto. The thumb grip extends radially from the spout and has the inner end thereof notched out as indicated NW. 4 t he handle and; at the, same time brlng the end of the oil box having the suction valve at 25 to' receive the spout and the outer end thereof positioned directly over the handle of the can. In this way the grip is 'con-' venient to the thumb when one is'hold-ing the can by the handle and the spout forms a guide preventing the rotation of the thumb grip. A coil spring 26 is interposed between the plunger and'the bottom of the 190x12, this. spring acting, to normally mainr in the plunger n "itsiupper" pastrie with in the r zylinder. i

The pump. unit is placed in, the can by initially tiltingfit to, permit the oilbox to enter the can. After one ha s the box in the can be bringsthe spouttothe vertical position and then lowers the pump until, the

plate 9 is seated on the collar. At this, time the oil box is lower thanj the partition 7 so that by" rotating the p ump, one bring the thumb; grip to its" proper, position above therein towards the side ofthe can remote from thefhan dle. The abovefbeing a c co np lished one firmly fastens the pump in place by screwingdown thexcap 8.

l When the can is to bel used one grasps the handleand "ang r, grip with, the. hand and places his thumbfo'n the euterend of l the'thumb grip, "Then by alterilatelyfpressmg, down the thumb grip and releasing'the same the oil is forcibly. expelled: through thefspout. Inthe down goingfniovementof the plunger the oil; previously drawn into the oil" box is forced upwardly into the spout, past the check valve] In the upgoing movement of the plu'nger'under the action out the spring; 26 Onis drawn inwardly through the suction valve to, fill the boxftvhich oil/is subsequently expelled in the down stroke ofthep lungenthe suction valve then closing and the check valve openin'g.

' This device will-discharge practically all oil from the (m. i The oil'box is close 'to the bottom so that whenthe can "is in the vertical p'ositionand the oillevel is low the oil willbe drawn into thefbox on the up-stroke of the plunger; Should the can he tilted forwardly into the horizontal positionor an inclined position between the horizontal and the vertical, there is oil trapped between the partition and the bottom'of the can, which oil will be drawn into the pumpon the suction stroke, even oil in the can.

As the pump can be removed as a unit it is a very easy matter to inspect the same, as occasion requires. 7

' What I claim as my invention is:

The combination with an oil container, said. container being fitted with a handle and being provided at the top with a comparatively. large, opening and having the openingsurrounded by a screw threaded Yupstandlng'flange, of a closure plate mounted on said flange and closing the opening, a cap screw threaded to the flange and fastening. the plate in position, an oil delivery spout carried by the plate and extending downwardly towards, the bottom of the can, an" oil box; passing transversely of the bot tom of. the container and opening to and -plunger and passing slidably through the closure plate and a thumb grip secured to the upper end of the rod, guided, by the spout and having the outer end thereof positioned above and within convenientrange of the handle.
